A CH question and I missed it. Been kind of busy with the new throttle quadrant. Well, maybe better late than never. For the VPPro, especially if you're using 2K/XP you should be using the new analog drivers (CHANLG08.EXE on the CH site). They work in '98, too. Anyway, they get rid of the double-POV nonsense in XP and provide their own calibration applet which included the adjustments that were in CTFJ 3.x so you can set the response, etc. if you want to. Do be sure to center the trim adjustments before you calibrate, if they're off center you just end up with an increased sensitivity in one direction or the other and it makes it harder to fly. Anyway, the calibration applet that comes with the drivers will show you the info that JCenter used to give.
If you need help with CH stuff, you'll probably get it more quickly over at:
